Yurul, Gokhan; Demri, Sukru; Gürger, Murat; Key, Sefa; Say, Yakup; Senel, Ahmet
Amaç: İskelet sistemine ait tüm kırıklar içerisinde %10 gibi bir oranla nispeten sık görülen ayak bileği kırıkları kalça kırıklarından sonra alt ekstremitenin en sık görülen ikinci kırık türüdür. Bu çalışmada, medial malleolün transvers kırıklarında medial malleol plağı, hazır gergi bandı, malleol vidası yöntemlerinin biyomekanik olarak karşılaştırılması amaçlanmıştır. Yöntemler: Kasaptan, insan tüketimi için kesilmiş, yumuşak dokularından arındırılmış 42 adet inek tibiası temin edildi. Çalışma kapsamına alınan kemiklerin medial malleollerine kesici motor yardımıyla transvers kırıklar oluşturuldu ve her biri 14 kemikten oluşan 3 gruba ayrıldı. Bu 3 gruptaki oluşturulmuş olan medial malleol kırıkları hazır gergi bandı, malleol vidası, medial malleol plağı kullanılarak usulüne uygun tespit edildi. Örnekler laboratuvarda çekme kuvveti ve transvers kuvvet uygulayan test cihazında hazırlanmış aparatlar yardımıyla biyomekanik analize tabi tutuldu. Alınan veriler kuvvetdeplasman eğrilerine dönüştürülerek yorumlandı. Bulgular: Çekme kuvvetinde medial malleol plağı yöntemi, 2 mm deplasman kuvveti ve katastrofik hasar kuvveti açısından diğer yöntemlere göre daha yüksek kuvvetlere dayanırken, dayanıklılık açısından hazır gergi bandı yöntemiyle arasında fark bulunamamıştır. Medial malleol plağı yönteminin çekme kuvvetinde malleol vidası yöntemine göre daha dayanıklı olduğu görülmüştür. Tranvers kuvvet uygulanan gruplarda 2 mm deplasman kuvvetinde medial malleol plağı yöntemi, hazır gergi bandı ve malleol vidası yöntemlerine göre daha yüksek kuvvetlere dayanabilmiştir. Transvers kuvvetlerde medial malleol plağı yöntemi, hazır gergi bandı ve malleol vidası yöntemlerine göre daha dayanıklı bulunmuştur. Sonuç: Medial malleol plağı medial malleolün transvers kırıklarında uygulanabilecek bir yöntem olup bu yöntemin olası dezavantajları için yapılacak başka çalışmalara ihtiyaç olduğunu düşünmekteyiz.

Turgut, Yigit Emrah; Kopuz, Tuba; Aslan, Alper; Toksoy, Seyhan Eryilmaz
In this study, it was aimed to determine the factors affecting parents' share on social media about their children. This is a qualitative study which was conducted with the participation of 88 parents. Data were collected through an online questionnaire consisting of open-ended questions. It was revealed that most of parents participating in the study posted about their children on social media. It was determined that parents mostly pay attention to the children's appearance and privacy while sharing posts regarding their children on social media. It has been observed that among the factors affecting sharing, the factor of staying in contact with the social environment of the parents stands out. Besides, some parents' desire to make special days permanent and the fact that their shares make them feel happy were other factors which draw attention. It was concluded that the parents did not have sufficient knowledge about the legal processes that may arise from their social media posts.

Akbaba, Emel; Aydin, Sevinc; Sanyurek, Nesrin Karaca
Vitis vinifera L. is cultivated throughout the World including Turkey which is one of the largest producers of grape. Grape is consumed as fresh or dry fruit as well as used in the wine industry in which good quality of grapes are preferred. Grape is also a part of the traditional Mediterranean diet which is linked to a low risk of cardiovascular and degenerative diseases. Kohnu is a geographically labeled type of grape cultivated in the eastern cities of Turkey. In this study, Kohnu grapes harvested from two different cities of Turkey were compared through phenolic compounds, phytosterols, vitamins, fatty acids, and antioxidative properties. The concentrations of phenolic compounds in the sample from Elazig were obtained to be significantly higher as compared to the sample from Malatya. Especially vanillic acid was found to be much higher in Elazig samples. The concentrations of fatty acids especially palmitic acid, palmitoleic acid, oleic acid, and linoleic acid were obtained significantly higher in Elazig samples as compared to Malatya samples. Vitamin and phytosterol concentrations of the samples from Elazig were also determined as higher as compared to Malatya samples. Significantly higher antioxidant activity of Kohnu grape seeds from Elazig was obtained via DPPH radical scavenging activity and MDA levels. The antioxidant profile of Kohnu grape seeds of Elazig samples could be related to phenolic composition and vitamins.

Ates, Mehmet; Yilmaz, Ersen; Kar, Bulent; Durukan, Ilknur Kars
Recent advancements in nanotechnology have garnered increasing attention due to the improvements in producing and utilizing particles whose sizes are extremely small. There is particular interest in metal nanoparticles due to their distinctive properties. Silver nanoparticles (Ag-NPs) have been of particular interest owing to their unique electrical, optical and physicochemical properties as well as their biomedical applications. Ag-NPs are the fastest growing class of nanoscale materials because of their antibacterial activities. They are now considered to be the next generation antimicrobials. Today, owing to their disinfectant properties, Ag-NPs are extensively used in numerous consumer products, including disinfecting medical devices and home appliances, paints, optical devices, plastics, textiles, soaps and laundry detergents, cosmetics, health-care products, as well as in food packing and food products as preservative and anti-caking agents. Despite their widespread usage, the products containing Ag-NP additives are a serious environmental and human health concern because of their toxicity. Studies on cell and bacterial cultures have shown that Ag-NPs are toxic; and the toxic effects are mainly due to the dissolved Ag ions when Ag-NPs degrade in water. In this study, considering the criteria outlined above, the purpose of the study and Ag-NPs were chemically synthesized in the laboratory environment and modified as chitosan coating. UV-Vis spectroscopy, transmission electron microscopy, scanning electron microscopy, X-ray crystallography and zeta potential analysis were used to characterize the silver nanoparticles.

In this study, three hybrids of Origanum (Lamiaceae) were examined in detail using morphological, karyological, palynological and molecular approaches. One of the three hybrids, O. × aytacii, is here described for the first time, and is compared with its putative parents, O. sipyleum and O. vulgare subsp. hirtum. In addition to morphological, karyological and palynological features, we also examined nuclear ribosomal DNA (ITS) sequences of O. × intermedium (O. onites × O. sipyleum), O. × intercedens (O. onites × O. vulgare subsp. hirtum) and their purported parental species that share the same area with the new hybrid. Pollen grains were hexacolpate and isopolar. The range of Polar/Equatorial ratio (P/E) of pollen for investigated taxa varied from 0.74 to 0.99. All investigated taxa are diploid with a chromosome number as 2n = 30. According to molecular results, O. × aytacii was the most polymorphic taxon. In addition, DNA sequences showed that O. × intercedens was more similar to O. vulgare subsp. hirtum than to O. onites, and O. × intermedium was more similar to O. onites than to O. sipyleum. Furthermore, O. onites and O. vulgare subsp. hirtum have many different ITS haplotypes, probably resulting from backcrossing with different individuals. Results obtained in this study demonstrate that hybridization has played a major role in the process of Origanum speciation.

Gul, Muhammet; Guneri, Ali Fuat
The increased focus of people on the quality of health care in recent years has led hospital owners to develop strategies and policies to improve medical services through the establishment of new hospitals. For hospitals to be competitive, the hospital's location and proximity to potential patients are considered crucial factors in establishing new hospitals. In this context, evaluating and selecting the most suitable hospital location to establish a new hospital from the multicriteria decision-making (MCDM) perspective is a priority for the entrepreneurs or government to gain a competitive advantage. Therefore, this study aims to present a systematic literature review of the hospital location selection problem considering the applied methods and application areas. The preferred reporting items for systematic review and meta-analysis statement (PRISMA) are used as a reference framework. Initially, known electronic databases (Web of science, IEEEXplore, Scopus, Science direct, and Google Scholar) were searched up to the early 2021. A number of 47 articles are selected and analyzed under this systematic framework based on inclusion-exclusion points. State-of-the-art developments in adopting MCDM methods and their fuzzy extensions are summarized. All the articles have been examined in a systematic taxonomy to find answers to six research questions (trend, country of origin, outlet journal, MCDM methods used, MCDM environment and criteria type, and decision criteria used). Results show that (1) AHP and GISbased MCDM models are the most contributing approaches to the solution of this problem, (2) location selection criteria are mostly cost, demand, environment, population, government, competition in the market, and distance to some important places, (3) the fuzzy structure is also preferred in addition to the MCDM structure depending on the crisp data type, and (4) the location selection criteria are mostly considered subjective. We pay attention to promising directions that can dominate future research in this field from a methodological or applicability perspective. This study shows the current views and opportunities for researchers and practitioners and acts as a guide to encourage more creative studies in this field.

Fatty acid (FA) profile of anaerobic fungi comprises carbon chains of length ranging from 10 to 22 were analyzed as methyl esters. Analysis of fatty acids was performed using Gas Chromatography-Mass Spectrophotometer (GC-MS). FA measures are presented as proportions of relative amounts (% total fatty acid). The highest amounts of fatty acids for all samples were found as myristic (C14:0) acid. The tridecanoic (C13:0) acid represented the second abundant FA in the fungi in all experimental groups. Stearic acid (C18:0) was the third major fatty acid for isolates investigated in the current study. In addition, another fatty acid was palmitic (C16:0) acid with relative amount representing >20% of total FA in all samples. Pentadecanoic (C15:0) acid could not be found in any other samples except Orpinomyces sp. (GMLF5). It is concluded that biohydrogenation of fatty acid composition by anaerobic gut fungi are very variable.

Natural products have historically been invaluable as a premium source of therapeutic agents. Recent advancements in genomics and structural biology have portrayed a high-resolution landscape of the diversity of proteins targeted by pharmacologically active products from natural sources. Natural product research has generated valuable wealth of information and cutting-edge research-works have leveraged our conceptual knowledge altogether to a new level. Wogonin (5,7-dihydroxy-8-methoxyflavone) is an O-methylated flavone and has attracted noteworthy appreciation because of its ability to pharmacologically target plethora of cell signaling pathways in different cancers. In this mini-review, we have gathered scattered pieces of available scientific evidence to summarize how wogonin pharmaceutically targeted Wnt/β-catenin, JAK/STAT, VEGF/VEGFR and TRAIL-driven apoptotic pathways in wide variety of cancers. We have also critically analyzed how wogonin prevented carcinogenesis and metastasis in tumor-bearing mice. Although researchers have uncovered pleiotropic role of wogonin in the regulation of different oncogenic signaling cascades but there are visible knowledge gaps in our understanding related to regulation of non-coding RNAs by wogonin. Future studies must converge on the unraveling of additional drug targets for wogonin to achieve a fuller and realistic understanding of the chemopreventive properties of wogonin.

Gürler, Nedim; Torğut, Gülben
In this study, PSG composite films were prepared by casting method by adding graphene (G) to glycerol plasticized potato starch (PS) films. The structure and properties of the composite films were investigated attenuated total reflectance Fourier transform infrared (ATR-FTIR), X-ray analysis (XRD), and swelling capacity, total soluble matter, transparency, tensile strength, and electrical conductivity. When the G content of PSG composite films increased from 0% to 1%, tensile strength increased from 1.035 MPa to 1.681 MPa, but decreased to 1.175 MPa in composite films containing 2% G. It also increased electrical conductivity when the G concentration increased. Also, the G layers are among the PS films and their swelling and solubility properties are reduced. With increased G concentration, the light transmittance decreased and the films were more opaque. These improvements can refer to the interface interaction between PS and G.

Background/aim: This study was conducted to elucidate the effects of lutein/zeaxanthin isomers (L/Zi) on lipid metabolism, oxidative stress, NF-κB/Nrf2 pathways, and synaptic plasticity proteins in trained rats. Materials and methods: Wistar rats were distributed into four groups: 1) control, 2) L/Zi: rats received L/Zi at the dose of 100 mg/kg by oral gavage, 3) exercise, 4) exercise+L/Zi: rats exercised and received L/Zi (100 mg/kg) by oral gavage. The duration of the study was eight weeks. Results: Exercise combined with L/Zi reduced lipid peroxidation and improved antioxidant enzyme activities of muscle and cerebral cortex in rats (p < 0.001). In the Exercise + L/Zi group, muscle and cerebral cortex Nrf2 and HO-1 levels increased, while NF-κB levels decreased (p <0.001). Also, L/Zi improved BDNF, synapsin I, SYP, and GAP-43 levels of the cerebral cortex of trained rats (p < 0.001). The highest levels of BDNF, synapsin SYP, and GAP-43 in the cerebral cortex were determined in the Exercise+L/Zi group. Conclusion: These results suggested that exercise combined with L/Zi supplementation might be effective to reduce neurodegeneration via improving neurotrophic factors and synaptic proteins, and oxidative capacity in the cerebral cortex.

Free radicals are responsible for many health problems, especially oxidative stress-related diseases. With conscious nutrition and the use of natural antioxidants, it is now possible to cope with these diseases or minimize their effects. The aim of this study was to determine pH, total acidity, total SO2, free SO2, relative SO2, dry matter, density, alcohol content, reducing sugar, ash, CUPRAC, DPPH free radical scavenging capacity, total phenolic content, elemental composition, and some phenolic compounds of Syriac (Mardin) wines. Estimated daily intake (EDI), target hazard quotients (THQ), total target hazard quotients (TTHQ), and relative risk (RR) were calculated, to assess a health risk resulting from regular consumption of Syriac wines. The elements EDI values through consumption of wines were less than the recommended dietary allowance values. Obtained THQ values were less than 1. When the obtained results are compared with the levels set by regulatory authorities, the investigated wine consumption does not pose a toxicological risk based on EDI, THQ, TTHQ, and RR values. In addition, this study showed that the Syriac wine’s antioxidant capacities are high and rich in phenolic compounds and elements.
